We do a version of this with our clients, where we use our forecasting software and host a "live" forecasting session. We make people forecast "cold" on something: likelihood of hitting milestones, competitive intelligence, industry trend, whatever, and then have someone come in and give a talk on what we've asked people to forecast. We follow that up with more forecasting and get to see if people were influenced by the expert or not.

Perhaps the most valuable part is the discussion after making that second forecast. We identify a lot of bias and assumptions people were making that they then learn from the next time they have to make a forecast like that.
